Theinvention aimslto provide a new, and irn' proved baking pan for baking elongated buns or rolls with a crust entirely, around the peripheri7 and onbothendsand the'pan consists ofhovel upper and lower sections detachably'connected in a simple and advantageous-manner. Figure 1 is a top-plan ,view of section of the improved pan.

Figure 2 is a bottom View of said Ibottom section. Figure 3 is a top lplan viewv of the top section. Figure 4 is a bottom view of said top section. Y Figures 5 and 6 are* enlarged detail vertical sections as indicated by the lines 5-5and'l-6 'of Figures -3 and 11'respectively, showing portions f of the Vtwo pan sections in juxtaposition.

Figure '7 is an enlarged vertical longitudinal sectional view through portions of the two pan sections assembled.

Figure 8 is a vertical transverse section on line 8 8 of Fig. 7.

Figures 9, 10, 11 and 12 are diagrammatic views illustrating some of the various transverse shapes struction will be specically described, minor variations may of course be made within the scope of the invention as claimed. f The lower section of the improved pan is indicated in a general way by the reference character I5, and the upper section lby the character IB, said lower section having a plurality. of separate, spaced, upwardly open semi-tubular pans I1 andV said upper section having separate, spaced, downwardly open semi-tubular covers I8 for said pans. The pans I'I and covers I8 'cooperate in forming separate tubular members eachof which is ,pe-

ripherally exposed throughout its circumference and length, whereby the oven heat when baking will entirely surround each of said tubular members to produce a thoroughlyand uniformly baked product. When the dough Vis placed'in the pans I'I of the lower section I5, the upper sectionY I6 applied, and theY dough baked, this dough of course rises and lls the pan covers I8, the pans and their covers then cooperating in forming molds for the buns or rolls being baked,- and these buns or rolls will have acrust entirely around the bottom ,Satanism-T" Y e to provide cylindrical-buns.or rolls, but the `shape y -Of @Saidpans and.

andigtw'o upper parallel; longitudinal-side bars 29 j extend acrossthe ends of the pancovers ;I8 and close same. The lower longitudinal edgespof the' l Aside bars AIll are bent horizontally inward'to pro-j vide flanges 2! which are secured against the bottoms of the pans I1, preferably by spot Welding as indicated at 22 inFig. 2.'v The upper longitudinal edgeportions ,ofgthese sameside bars I 9 are bent horizontallyioutward.to provide upper anges 23. The upper sidesof theseflanges are inthe same-horizontal plane with the upper edges of the pansY I'I `and saidiianges and-edges are spot-welded together in the present disclosure, as indicated at 2 4 in Fig. 1. IAt their outer longitudinal edges, the anges 23 kare providedwith Vertical flanges 25 which are `instrumental =in v properly alining the two pan sections I5 Vand I6. when assembling same. In inwardly spaced rela.

tion with the flange25, each flange 23 is equipped with rigidly attached upwardly projecting'studs f 26 for a purpose to appear.

The upper longitudinal edge portions ofthe 1 side bars 2D of the upper sectionxl, are bent horizontally inward to provide flanges 2l which are securedv upon the upper sides of thepan Y covers I8, spot welding being preferably employed here also, as indicated at 28 in Fig.` 3. l The lowerr longitudinal edge portions' of the side bars 20 arel bent horizontally outward to provide' anges 29 f to lie upon the flanges 23 as'seen in Fig. 8, these flanges 29 being formed with openings :3U `to receive the studs 25 above described. f By simply resting the upper section I6 of the pan upon the lower section', with the edges of the flanges 29 against the inner sides of the flanges 25, and

longitudinally sliding said upper sectionk with, respect to the lower section to the proper extent, the openings 30 will aline with the studs IB and said upper section will drop'into position upon said lower section. Attention is invited` to the fact that the flanged sidebars I9 and 20 are not Y connected at their ends by' any flanged end bars.

their peripheries and on both ends, tending to keep their interior portions fresh for an unusual length of time. -In the main views, the pans I'I and covers I8 are each oisemi-cylindrical form This materially simpliiies construction and facilitatesplacingfof the cover section'upon the lower section by a longitudinal sliding movement, which movement is limited at the proper time by the gravity-affected engagement of the studs 26 and i openings 30. Itis thus possible to initially place I9 extend r the cover section upon the pan section without regard to longitudinal accuracy and to then longitudinally slide said cover sectionl upon said lower section until this sliding movement is limited by engagement of the studs and openings, the cover section being thus engageable more easily with the lower section.

The lower edges of the pan covers I8 are flush with theflowerzside ofthe anges #Brand said edges and anges are preferably :spot welded i together as illustrated at 3l in Fig. 4.
